It will be great if Nikon can provide a small firmware update with just the new iso auto implementation from the latest cameras (d800/d3200) onto the 1 generation older cameras (d5100, d7000, d300s, d700, d3s, d3x). Its ok to give this after they are done releasing all the cameras in this latest generation - so that there is not even a remote possibility of cannibalizing the sales from the upgraders who could go from say d7000 to d7200 (whatever the new camera name). But this small few line code change will generate a lot of extra customer goodwill without costing any lost sales (no one will change the upgrade plans just for an improved iso auto).
